Hello,

I need to get Freeswitch to detect when the caller has hang up, so it will hang up the ilne also. Especially important for when the caller has left a message, although ideally it should work for all calls.

With Asterisk this required the use of automatically detecting the busy signal, at the driver level. How can I do something similar with Freeswitch?

Some web pages suggest I use this:

<action application="tone_detect" data="busy 425 r 0 hangup 'normal_clearing' 3"/>

Unfortunately this has the side affect that it answers the call, I don't want to change the answer behaviour, only the hang up behaviour.

I also see this message, but so far no solution:

How do I do this?
